最近几年,一种新型的施工模具——柔性充气模板在美国建筑施工中得以广泛应用,特别是在钢筋混凝土曲面壳体结构的施工中,显示出了巨大的优越性。所谓充气模板是以柔性的并具有面层涂料的纺织品制成的充气体,在施工现场充以压缩空气使其按设计曲面成型并以此做为现浇混凝土的施工模板,待混凝土浇筑并获得一定强度后,即可放气拆模。使用这种模板,可配合喷射混凝土进行施工,对于采用预应力技术的大跨度结构,可在充气模板外侧铺钢筋喷射混凝土,对于有保温要求的仓库和住宅,则可在充气模板内侧先喷射隔热层,再架筋
In recent years, a new type of construction mold, flexible inflatable formwork, has been widely used in the construction of buildings in the United States, especially in the construction of reinforced concrete curved shell structures, showing great advantages. The so-called inflatable template is a flexible inflatable fabric with a surface coating made of textiles, filled with compressed air at the construction site to be shaped according to the design surface and as a construction template for cast-in-place concrete, until the concrete is poured and obtained After a certain strength, you can release the air and remove the mold. Using this kind of formwork, it can be used in conjunction with shotcrete construction. For long-span structures using prestressed technology, rebar shotcrete can be placed on the outside of the inflated formwork. For warehouses and residences with insulation requirements, they can be sprayed on the inside of the formwork. Hot layer, re-stretch
